Somebody asked for a series that sums to an algebraicirrational a time ago. With easy rational summands, of course.

And here is the easy answer: Compute the MacLaurinseries of sqrt(1+x). Terms are like 1*3*5*7/2*4*6*8or the like. I hope x=1 is within the convergenceradius (and if not,x=1/2 surely is!)Thus you get a nice series for sqrt(2).-- Hauke Reddmann <:-EX8 fc3a501@math.uni-hamburg.de PRIVATE EMAIL fc3a501@rzaixsrv1.rrz.uni-hamburg.de BACKUP reddmann@chemie.uni-hamburg.de SCIENCE ONLY
